Reply To: Bad reaction to Privigen

Hi Sandra, sorry to hear that. I did have bad reactions to Ivig (Intragam) myself. One of them was swollen legs. It took about 4- 6 weeks for symptoms to start easing and about 4 months to actually get better. It basically needs the same time as it takes for IVIG to wear off under normal circumstances.
